 """
 The :mod:`navigator_drone_comm` module is used to communicate with the drone from Navigator.
+Packets received from the drone are published to /navigator_drone_comm/target, /navigator_drone_comm/gps,
+and /navigator_drone_comm/target.
+Can send packets to the drone by calling the services /navigator_drone_comm/estop, /navigator_drone_comm/stop,
+/navigator_drone_comm/start "example mission name".
